I was wondering if there's a page or link somewhere, that tells what wheel size can be run with what drop etc etc? I'm trying to find out if 20's will fit on my 09 GT/CS with or without a small drop? I'm currently sitting stock on the stock 18's. However, in the future I'd like to add a small drop to the car. I have a line on some nice wheels, but clueless if they'll fit without rubbing? Let me know what your thoughts are? is this to big of a wheel to run?

 

I ran 20's with an inch and a half of drop. No problem at all. Others are lower with 20's and fine as well. No problem.

Just for reference, when I had my 20's I was running -
P255/35R20 front
P285/30R20 rear

 

how far are you lowering it? I have a friend that has 20's with a 2" drop.

 

HUH?
Generally when you up the wheel size you drop the profile so that the overall diameter is the same, so there is no difference from stock. Now when you mess with offset and width then you can run into some issues.

 

Agree.

My 20's were wider than stock on rear. My fronts were high offset to clear Brembo calipers. Still no issue.

OP - unless you are planning to SLAM the mustang, the you are going to be fine with 20's........

 

Dont forget your speedo calibration!.. damn I remember a site that I used to input the tire and rim sizes and it would tell you how off your speedo will be... it was booked marked on an old PC I went office space on.

 

20s are heavy and will slow your car down. Something to think about.

 

I was only thinking about a 1" or 1.5" drop. The wheels I'm looking at are the Foose 20 x 8's I think. A friend is selling them new for about half price. Thanks guys!

 

Wheel size is 20x 8.5 cost is $1200 for all 4 of NEW Foose Nitros. I was wondering if anybody could post up some pics of their ride with the 20's mounted? I'm really having a hard time pulling the trigger on these wheels, yes, it's a good price. However, I'm a picky bastard and really would like to see what it'll look like. Oh, if you could let me know what size ties should be run on these as well, so I can get a quote. Thanks guys, "LAdies?"

 

Just out of curiosity, hows the ride? Did you lose anything? Stiffer ride? I'm sure the responsiveness in cornering got improved? Let me know.
